First of all greetings. I am new to the list, I have been reading it for a while but now is my first post. I have a question regarding gauges of magnet wire. I recent aquired a 10# spool of 18AWG magnet wire from a local surplus store, what I am wondering is if there are benifits to using a larger wire size versus the 21AWG I normally use? Would this size of wire be better for a magnifier than a 6 or 8" secondary? Thanks, Jason Zuberer
